I'm checking out Kiwi. No, not the browser, Nostr.Kiwi a browser based nostr client.

As far as things that stand out... Communities (like Amethyst, but some different ones from eachother and a few the same) Also "Lists". In your feed, you can click on the user's profile picture, get a dropdown menu, and add the user to a list, without having to go to their profile. Nice flow!
